The creation and management of metadata documents can be quite a difficult task to accomplish manually. To address this issue in the context of the EBUCore v1.3 metadata set, we propose a GUI-based metadata editor, called QEbu, developed during the Multimedia Archival Techniques course, held at the Polytechnic University of Turin in collaboration with RAI. QEbu was developed with the aim of providing a user-friendly graphical editor to create and manage XML documents, relieving the user from the burden of worrying about the structure of the data and letting him focus on the actual content. The editor is usable by both experienced users and novices in the field. QEbu has been developed in C++ using the cross-platform and open source library Qt 4.8; this framework was chosen in order to exploit its natural features for developing interface-centred applications, running locally on the machine of the user under a desktop environment.
